When I awoke, the summer dawn was stealing faintly through the barricaded windows. Oh! how I longed for one draught of air, even as London imports it! My head was burning and my eyes distended from the tainted stuff around me, and my hands, and arms, and even shoulders were stiff from over exertion. Languidly regarding the brick I had worked so hard for, and commiserating much the plight of my tender hands, I felt inclined to give it up, till I thought of all at stake. My poor Uncle in deadly peril through my desperate folly; Conrad too, as that murderer implied, in a critical position. My own life also--it might be a week before the monster returned; and I felt sure that I could not live more than three days in that corruption. The oppression was so horrible, especially when I stood up, that I resolved at all hazards to break one of the windows. I had tried to do so the night before, but they were beyond my reach, and I had no stick, for I durst not touch the poles that propped the unlucky porpoise. Now, I had a good missile, and after two or three vain attempts from the closeness of the bars, I hurled the brick-bat through the glass; and, as it raised the sacks a little, I obtained more light, as well as a breath of air. The taint upon the glass, the reek of the deadly gases, even cleared away for a short distance round the fracture.
Cora was fast asleep no doubt, and the crash of the glass did not disturb her; so I fell to again, and worked very hard till breakfast time. If I could only get out by noon, in time for the two o'clock train! When I expected my jailor, I hid away under the porpoise the seven bricks I had removed since daylight--for I could work much faster as the aperture increased--and then I fastened my blanket over the hole. After drinking the milk with some relish--eat I could not in that pestilential den--I returned to my labour, and prepared to attack the second course in the thickness of the wall. By this time I had contrived, with the help of a brick, to extract the hold-fast from the bench, which I could not do the night before; and very useful I found it, both as a hammer and lever. So with rising hopes, I resumed.
Oh, cruel disappointment! The second course was bedded in cement harder than the bricks themselves. Most likely they had formed the outside of the wall, until Lepardo added the nine-inch lining of headers. I was utterly dismayed; and now my beloved knife, which had stood like a hero-martyr all its grinding indignities, broke off short at the haft, and left me helpless and hopeless. And I was getting on so well, and so proud of all I had done. There was nothing for it but a storm of crying. It served me right for ill-treating my dear father's knife so shockingly.
